Locomotive HEAD-LtGHT.

SPECIFICATION forming part of Letters Patentlvo. 273,428, dated Maren e, 1883.

Application tiled January 13, 1883.

To all whom fit may concern:

Be it known that we, JAMES ALLEN and WM. ROSS MUSSER, citizens of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Locomotive Head- Light, of which the following is a speciiication, reference being had to the accompanying drawings.

This invention relates to head-lights for lo-v comotives; and it consists in certain improvements in the construction and arrangement of the same, the object of which is to enable the head-light to be simultaneously moved to either Aside of the stack and reversed, so as to throw nal vertical sectional view, and Fig. 6 is a vertical transverse sectional view on the line a0 x in Fig. 5. v

The same letters refer to the same parts in all the figures.

In the drawings, A designates the locomotive, the front end of which has brackets B B, bolted or otherwise secured to the boiler.

C is a frame or table mounted upon the brackets B B, and having a dovetailed slot, D, in which slides a block, E, upon the upper side of which is bolteda plate, F, carrying the lamp or head-light. The latter, which is denoted by letter G, is mounted upon a plate, H, having a stem, I, swiveled in the plate F and block E. The stem I has a pinion or spur-wheel, J, capable of engaging racks K K near the ends of the frame O, at the rear edge ot' the latter, so that when the head-light is moved to either end of the frame from the center it will be given a half-turn. At the rear edge of frame C is also a central flange, L, which, when the light is at thecenter ofthe frame,bears against the plate J, thus preventing the light from turning. i

M M are tubes running alongside the boiler from the frame C to the engineers cab, and

(No model.)

serving as hand-rails. The underside of fratne G is provided with horizontal sheaves or pnlleys N, located at the front ends of said tubes, and with additional sheaves O, located near the ends of said frame. The under side of the block E is provided with lugs P P, to which are attached ropes or chains Q. passing over the sheaves O N Aand-through the tubes M to the cab, where they are wound in opposite directions upon drums B. B, ixed upona transversen shaft, S, which may be conveniently operated by means-of a crank, T.

The head-light or lamp may be of any suitableconstruction; but we prefer to provideitin the rear side of the casing with a red glass, U, serving as a danger-signal when the lantern is reversed.

The ends of the frame C have brackets V V, in which are mounted rollers W, over which passes a belt, X, which extends under the said frame, and the ends otwhich are attached to the pla-te or carrier F by means ot' studs or spurs Y, formed upon the latter. This belt serves to protect the operating parts and prevent them from being clogged.

The operation of our invention will be readily understood. By turning the shalt S the head-light may be moved to either side, and at the same time reversed, so as to throw the light in a rearward direction, and at the same time present a danger-signal in front. hen the head-light is moved'to the center, the smokestack conceals the danger-signal.

We would haveit understood thatothermechanism than that herein described may be used for moving thehead-light to either end of the frame without departing from the spirit ot' our invention.

We claim and desire to secure by Letters Patent ofthe United Statesl. vThe combination, with a locomotive having at itsV front end aV transverse frame or table, ot' ahead-light arranged to slide upon said table and to be at the same time revolved, substantially as set forth.

2. The combination, with a locomotive hav ing at its front end a transverse frame or table, of a head-light arran ged to slide upon the said table and to be at the same time revolved byl means of mechanism substantially as de-` scribed, said head-light being provided with IOO a red glass or (langer-signal in the rear side of its casing, as set forth.

3. The combination, with a locomotive having at its front end a transverse frame or table, of a head-light mounted upon the said frame or table, and mechanism wherebythe said head-light may be moved to either end of said frame, and at the same time be caused to make a one-half revolution, so as to present its light in a rearward direction, substantially as set forth.

4. The combination, with a locomotive having at its front end a transverse frame or table, of a head-light mounted upon the latter, said head-light being arranged to revolve, by means substantially as described, in a horizontal plane when moved toward either end of the frame, and a flange arranged at the center of said frame, so as to prevent the said headlight from revolving while at the center ofthe frame, substantially as set forth.

5. The combination of the locomotive, the transverse slotted frame having racks at either end and a centrallvlocated flange, the block or slide having a plate or carrier on its upper side, the swiveled head-light having a stem provided with a pinion engaging the racks, and mechanism for moving the block or slide toward either end ofthe frame, as set forth.

6. The combination ofthe transversely-sliding block carrying the head-light, the guide sheaves or pulleys, the tubular hand-rails, the transverse shaft having winding-drums, and the operating cords or chains, all 'arranged substantially as described.

7. The combination ot' the slotted frame or table provided at the ends with brackets, rollers mounted in the same, the sliding block carrying the head-light, and a belt or band cxtendng around the frame or table, and having its ends attached to studs formed upon the upper side of the carrier-plate, substantially as set forth.

In testimony that we claim the foregoing as our own We have hereto affixed our signatures 45 in presence of two witnesses.

JAMES ALLEN. WM. ROSS MUSSER.
